Traditional ICF systems’ installation is tedious and labor intensive resulting in out of
level, bowing, and snaking walls with a significant amount of bracing adding to the cost.
Traditional ICF blocks also have built-in weakened planes because of the massive
amounts of horizontal and vertical joints and attachment points are limited for
fastening interior and exterior finishes.

ICF (Insulated Concrete Form) walls are a form of structural walls used for construction.
Hobbs Vertical ICF system uses less concrete, more recycled material and requires less
labor for construction. The furring assemblies and retainer clips of the Hobbs VICF
system are made from 100% recycled post-industrial waste.

There are two wall designs- contoured and flat- as shown below. Flat wall designs can be used around
window and door openings as well as for additional structural strength along with contour walls.

 Retainer Clips(see Figure 5)
 Base Angle (see Figure 6)
 Performed Corner Assembly (see Figure 7)
 Tees (see Figure 8)

Uses 40% less concrete and 39% more insulation than typical ICF blocks.
It uses components consisting of materials derived from recycled content and is considered to be the
most environmentally friendly ICF system available

The Hobbs system “contoured design” achieves a superior insulation value by using less concrete and
more foam insulation
Energy-efficient design means a reduction in the size and cost of HVAC equipment – which could
translate to saving of 50-70% in utility costs every month of every year. The unique vertical panel
system is a one piece, full wall height; formers can work primarily from the ground, resulting in a safer,
faster, and easier assembly
It has been tested by third party physical testing-Iowa State University- to verify its strength
According to Hobbs, the following table shows a sample of the savings incurred when choosing the Hobbs
ICF compared to a regular ICF (Hobbs Vertical ICF, 2014).

Hobbs Building Systems has received a U.S. patent for their "Hobbs Vertical ICF Wall System" and has been
used on a number of projects by homeowners and contractors.
